XPS 9510, BIOS 1.22.0, I can no longer turn on my via U4021QW
After the update of latest BIOS 1.22.0 on my Dell XPS 9510 I can no longer turn on my computer via the power button on the Dell U4021QW monitor. I have to unplug the thunderbolt and plug it in again to turn on computer.
This has been working fine in previous BIOS versions.
I usually keep my computer in my laptop stand and I shutdown the computer via Windows 10, as normal. Then in the morning I have always just pressed the power button on the U4021QW and everything would start as normal. Computer turns on and a few seconds later the screen turns on.
I now have to unplug laptop - turn it on - then plug i in again to get up and running. Just a bit annoying as this has been working great previously.
